RAIL-ANCHOR.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Appucation mea september 19, 191s. serial No. 120,918.

Toledo, Lucas county, Ohio, have invented new and useful Improvements inRail-Anchors, lof which thefollowing is a specification, reference beinghad tothe accompanying drawings, in which- `igure 1 is an elevationshowing my 1mproved anchor applied to a rail and illustrating the railin section; Fig. 2 is a plan thereof; Fig. 3 is an elevation of thewedge; Fig. 4 is a partial elevation similar Ito that of Fig. 1 butshowing a 'modification of the wedge; Fig. 5 is an elevation 0f avmodied form of my device; Fig. 6 is a plan thereof; Fig. 7 is anelevation of the wedge, and Fig. 8 is a partial elevation, similar` toFig. 4 githa wedge of the character shown in My invention relates torail anchors and consists in a base plate and wedge construct- -ed andarranged so as to prevent the rail from creeping. y y

Referring to the drawings,.A indicates a rail section, B a base plateand C the wedge. The plate B has a rall-base engagin jaw 2 and a wedgeengaging jaw 3, and a epending foot or abutment 4 intended forengagement with a tie (not shown). Underlying the edge of the rail-baselon the side engaged by the wedge is a depression 5 in the plate B.

The wedge C consists of av jaw 6" which engages the up er and underfaces of .a

ange of the rail A and in a wedging facer 7, inclined both to thelongitudinal' axis of the rail and to a horizontal plane, 'and engagesthe correspondingly-inclined c inner face 8 of the jaw 3 on thebase-plate B. The outer end of the wedge is provided with an abutment 9by which it is driven into; place and with a lug 10 on its inner end bywhich the wedge may be driven out in disengaging.

the fastener from the rail. The lower portion 11 of the jaw 6 extendsunder the rail ange in the depression 5 of the base plate B. The facesof the jaws 2 and 6 which engage the rail flanges do not diverge assharply as the faces of the ra'il which they grip so that as the wedgeis driven into position the two jaws will be forced slightly apart andthus exert a tight springing grip upon the rail base.

In applying the fastener to the rail the plate B is first placed inposition with its jaw 2 engaging one of thebase flanges of the rail.Thewedge C is then driven in and as its inclined side 7 engages thecorresponding. inclined face 8 on the jaw 3 it is wedged against onerail flange and draws.

the plate B and the jaw 2 against the other rail Harige.' At the sametime the movement of the wedge C, because of the inclination of thefaces 7 and 8, forces' the wedge C down upon the rail base so as to holdthe rail base and the'base of the plate B firmly together. Thehorizontal surface 12 on the plate, however, prevents further downwardmovement of the wedge C relative to the plate B so that the inwardmovement of the wedge caused by the surfaces 7 and S'results in algorizontal movement thereof toward the rail ase.

As the wedge is driven in, the point 13 of the Jaw 3 receives themaximum horizontal pressure of the wedge and is in horizontal alinementwith the edge of the rail so that there 1s no twisting action upon thewedge, and the bending stress imposed by the wedge on the jaw 3 is alsoreduced to a minimum because the depression 5 in the base permits theapplication of pressure to the jaw 3 at a point substantially inalinement with the surface 12. To prevent the lower portion 11 of thejaw 6 from striking the tie when the wedge has been driven into appliedpo' sition, the part is cut oif at 14, as is shown in Fig. 3. 4This isof particular advantage either where the fastener is used-on anundersized rail, or where the anchor has been used to such an extentthat the parts have become distorted, and therefore can be driven infarther than is shown in the drawings.AN

Figure 1 shows the wedge G engaging the lateral edge as well as thetop'and bottom of the rail base so that its lateralpressure upon therail base is resisted by a -direct contact with the .edge of the base,as well as by the wedging grip upon top and bottom of the base. In casea direct pressure upon the edge of the base is not desired, thewedge maybe constructed as lshownin Fig. 4, which shows the wedge gripping onlythe top and bottom of the rail base so that its contact with the baseis' purely a wedging one. i

n Figs. 5, 6 and 7 I have shown a modi- Y, which the wedge C3 grips onlythe top and bottom ofthe rail base, so that, as in Fig. 4c, its contactwith the base is purely a wedging one.

The terms and. expressions which I have employed are used as terms ofdescription and not of limitation, and I have no intention, in the useof such terms and expressions, of excluding any mechanical equivalentsof the features shown and described, or portions thereof, but recognizethat various structural modications are possible within the scope of theinvention claimed.

What I claim is:

l. In a rail anchor, a base member and a rail engaging member adapted tobe driven between one part of the base member and the rail, the railengaging member havin a jaw engaging upper and lower faces o the -railbase and being held from twisting yby a horizontal face in substantialaline- 'ment with the bottom of the rail.

2. In a rail anchor, a base member and a rail-engaging member adapted tobe driven between one part of the base member and the rail, saidrail-engaging member comprising a rail-engaging jaw extending within adepression in said base member, and a body portion seated upon ahorizon-` tal surface of said base member in substantial alinement withthe bottom of the rail.

3. In a rail anchor, a base member having oppositely disposed Jaws, oneof said jaws having a face inclined both to the longitudinal axis of therail and to a horizontal plane, ,a wedge having a corresponding facebearing against the face on Saidyja'w and being adapted to be forcedthereby against the face of the rail ange, said jaw also having ahorizontal bearing'substantially in horizontal alinement with the bottomof the rail and engaging a corresponding horizontal bearing on'thewedge.
